Abstract (en)
[origin: WO8602878A1] An injection molding machine which uses a servo motor (M) as a source for driving a mold-fastening mechanism (2) and which is provided with a mold protecting function. An NC control device (4) which drives the servo motor (M) has a torque limiting function, and limits the torque when it is detected that a predetermined position for protecting the metal mold is reached based upon the output of a position detector (P). Further, the NC control device (4) has a display device (10) which displays an alarm when a predetermined period of time has passed after the predetermined position for protecting the metal mold is arrived at but before a predetermined mold touch position is reached.
